The bug
If you right click with a glass bottle on the dragons breath particle and there is already a dragons breath bottle in your inventory, the new dragons breath bottle that is created stacks up with the other one. This does not happen when you use the last glass bottle in a stack.
How to reproduce
Summon an ender dragon with a custom UUID
/summon ender_dragon ~ ~ ~ {NoAI:1b,UUID:[I;1,2,3,4]}
Summon an area effect cloud with the ender dragon as owner
/summon area_effect_cloud ~ ~ ~ {Duration:2000,Radius:5f,Owner:[I;1,2,3,4]}
Right click the area effect cloud with at least two glass bottles
→ ❌ You will notice that the dragon's breath item created by the last used glass bottle is not added to the existing stack

@@unknown, could you please create a separate report for that in case none exists yet. We will link it to this report then.
Honey bottle is being tracked at MC-185779, but for some reason it was resolved as Cannot Reproduce, but I can still reproduce in 20w46a and 1.16.4
Confirmed for 1.13.1.
